Matches are weighted by importance: For example a Champions League match would be given more weight than a regular season Ligue 1 game.
The weighted mean difference reflects the difference in change from baseline to endpoint for active treatment compared with placebo, weighted by the inverse variance (ie, studies with smaller variance, and likely larger sample size, given more weight).
In these alternative methods, the value was imputed as the lower bound, the upper bound and weighted means giving more weight to the lower, or upper, bound.
The polynomial is fitted using weighted least squares, giving more weight to points near the point whose response is being estimated and less weight to points further away.
The weighted average approach gives more weight to features which can be considered more informative e.g. while information about cellular localization of a protein is important, a mouse model with a highly similar phenotype to query disease is a much stronger predictor of a good candidate disease gene.
The weighted average Jaccard index is weighted by family size and gives more weight to larger gene families and less weight to smaller gene families.
To combat this, the parameters could be weighted based on biological importance, giving more weight to parameter dimensions deemed important by the experimenter.
The fitting is carried out by the weighted least square regression, which gives more weight to points close to the target point and less weight to distant points.
The "weighted" component of the measures indicates that the covariance measure gives more weight to clusters that are composed of more gaze points (see Mital et al., 2010 for more details).
For all analyses, however, syntheses were achieved using a weighted linear combination of the study estimates so as to give more weight to studies of larger size.
